Michael Waldman, president of the Brennan Center for Justice, issued the following statement:

"On the census, the Trump administration’s lies went so far that even this Supreme Court had to say no. If this leads to a result with no citizenship question, that would be a very welcome outcome, and it would also preserve the status quo. This should have been an easy case, and in the end, it was.

"But Chief Justice Roberts’ ruling that no federal court can ever consider claims of extreme and unconstitutional partisan gerrymandering is truly appalling for the long term health of our democracy. It’s a judicial green light for egregious partisanship, a permission slip for politicians to entrench themselves without fear of judicial intervention.

"The Constitution is clear about what must happen now. We the people have the power to bar partisan gerrymandering. States and Congress can prevent it, and can create independent nonpartisan redistricting commissions. Voters enacted redistricting reform in five states last year. And the House of Representatives passed a national ban on partisan gerrymandering and a requirement for states to establish independent panels as part of H.R. 1, the For the People Act. Time is of the essence.

"Fixing our democracy now has been placed at the center of our politics by a Supreme Court that saw an unconstitutional situation and refused to do anything about it. It should be a topic at tonight’s debate, and all debates going forward."
